Kodi Buckling Restrained Brace ndi chiyani?
Buckling Restrained Brace (yomwe ndi yachidule ya BRB) ndi mtundu wa chipangizo chonyowetsa chomwe chili ndi kuthekera kwakukulu kotaya mphamvu.Ndichingwe chomangika mnyumba, chopangidwa kuti chilole kuti nyumbayo zisasunthike mozungulira, zomwe nthawi zambiri zimakhala chifukwa cha zivomezi.Amakhala ndi chitsulo chochepa kwambiri, chosungira konkire chopangidwa kuti chizithandizira pachimake ndikuletsa kugwedezeka pansi pa axial compression, ndi dera la mawonekedwe lomwe limalepheretsa kuyanjana kosayenera pakati pa awiriwa.Mafelemu omangika omwe amagwiritsa ntchito ma BRB - omwe amadziwika kuti mafelemu a braced braced, kapena ma BRBF - ali ndi zabwino zambiri kuposa mafelemu anthawi zonse.
Kodi chingwe chotchinga chimagwira ntchito bwanji?
Zigawo zitatu zazikuluzikulu za BRB zitha kusiyanitsa ndi chitsulo chake, chosanjikiza chotchinga ma bond, ndi choyikapo chake.
Chitsulo chachitsulo chimapangidwira kukana mphamvu zonse za axial zomwe zimapangidwira muzitsulo.Malo ake ozungulira amatha kukhala otsika kwambiri kusiyana ndi ma braces okhazikika, popeza ntchito yake siyimangokhala ndi buckling.Pachimake chimakhala ndi kutalika kwapakati komwe kumapangidwira kuti azipereka mopanda malire pakachitika chivomezi chopanga mapangidwe;ndi zolimba, zosalolera kutalika mbali zonse ziwiri.Kuwonjezeka kwapang'onopang'ono kwa gawo lopanda malire kumatsimikizira kuti kumakhalabe zotanuka, ndipo motero pulasitiki imayikidwa pakatikati pazitsulo zachitsulo.Kukonzekera kotereku kumapereka chidaliro chachikulu pakulosera za zomwe zimachitika komanso kulephera.
Chotsekereza chotchinga chotchinga chimachotsa choyikapo kuchokera pachimake.Izi zimathandiza kuti pachimake zitsulo zisagwirizane ndi mphamvu zonse za axial zomwe zimapangidwira muzitsulo, monga momwe zinapangidwira.
Chophimbacho - kupyolera mu kusinthasintha kwake - chimapereka chithandizo cham'mbali motsutsana ndi flexural buckling ya pachimake.Nthawi zambiri amapangidwa ndi machubu achitsulo odzaza konkriti.Njira yopangira choyikapo ndikupereka choletsa chokwanira chakumbuyo (ie kulimba) motsutsana ndi chitsulo chapakati.
Ubwino wa chingwe chotchinga ndi chiyani?
Maphunziro oyerekeza, komanso ntchito zomanga zomwe zatsirizidwa, zimatsimikizira zabwino zamakina otsekera zomangira (BRBF).Machitidwe a BRBF atha kukhala apamwamba kuposa zida zina zomwe zimawonongeka padziko lonse lapansi pakuchita bwino pazifukwa izi:
Zingwe zomangira ma buckling zili ndi machitidwe ochotsa mphamvu omwe amawongoka kwambiri kuchokera ku Special Concentrically Braced Frames (SCBFs).Komanso, chifukwa machitidwe awo ndi apamwamba kuposa machitidwe ena ambiri a zivomezi (R = 8), ndipo nyumbazo nthawi zambiri zimamangidwa ndi nthawi yowonjezereka, katundu wa zivomezi amakhala wotsika.Izi zitha kupangitsa kuchepa kwa kukula kwa membala (gawo ndi mtengo), kulumikizana kung'ono komanso kosavuta, komanso zofunikira zazing'ono za maziko.Komanso, ma BRB nthawi zambiri amamanga mwachangu kuposa ma SCBF, zomwe zimapangitsa kuti kontrakitala achepetse ndalama.Kuphatikiza apo, ma BRB atha kugwiritsidwa ntchito mu seismic retrofitting.Pomaliza, pakachitika chivomezi, popeza kuwonongeka kwakhazikika pamalo ang'onoang'ono (chinthu chapakati cha brace), kufufuza ndikusintha pambuyo pa chivomezi ndikosavuta.
Kafukufuku wodziyimira pawokha adatsimikiza kuti kugwiritsa ntchito makina a BRBF, m'malo mwa zivomezi zina, kumapangitsa kuti pakhale ndalama zokwanira $5 pa sikweya imodzi.
Ubwino wa chingwe chotchinga ndi chiyani?
Dongosolo loletsa kutsekeka kwa buckling sikungogwiritsidwa ntchito pomanga zatsopano, komanso kulimbikitsa ndi kukonzanso nyumba zakale zimadalira ntchito yake yabwino komanso mtengo wotsika.Minda yofunsira ili motere.
Nyumba zapamwamba / Mabwalo a ndege / Sukulu ndi zipatala / Misonkhano ndi malo owonetserako / Nyumba yomanga fakitale
